It depends on several factors

First - were you intoxicated to the point you could not rationally make decisions?
I would say "yes you were" because you blacked out due to the alcohol and were getting sick all through it.

Second, was there any point at which you told him you did not want to do a certain thing and he did it anyway? (Ex - did you indicate you did not want to perform oral?)

Third - was any kind of drug administered to you without your knowledge in an effort to cause this to happen?

Curious .. why are you worried he raped you? Generally that in itself is an indicator the answer is "yes you were raped" - unless there are outside influences.
